THE NORRIS PETERS C0 GEORGE MQEACHRON, OF IRON RIVER, MICHIGAN.

FLOUR-SIFTER.

Application filed March a, 1913.

To all whom it may concern 7 Be it known that I, GEORGE MCEACHRON, acitizen of the United States,.residing at Iron River, in the county ofIron and State of Michigan, have invented new and useful Improvements inFlour-Sifters, of which the following is a specification.

This invention relates to flour Sifters, and the prime object of theinvention is to produce a scoop sifter having a handle and an agitatorwhich may be operated by the hand grasping the handle, the whole beingof simple and improved construction.

A further object of the invention is to simplify and improve theconstruction of the agitator and the manner of mounting the same.

A further object of the invention is to provide simple and improvedmeans for actuating the agitator.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaim may be resorted to when desired.

In the drawing,-Figure l is a side elevation with parts broken away toshow the construction. Fig. 2 is a top plan view with a part of thehandle broken away. Fig. 3 is a perspective detail view showing theagitator and a portion of the cross bar supporting the same.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The scoop 1 has a flat screen bottom 2, and said scoop is provided witha handle 3. Fitted in the scoop directly above the screen bottom is across bar 4 affording a support for the agitator 5. The latter element,as will be best seen by reference to Fig. 3, is formed of a single pieceof wire, the same being bent in an approximately horizontal plane toform a plurality of loops 6 substantially radiating from a commoncenter, one limb of one of the loops being extended Specification ofLetters Patent.

inwardly to said center and bent to form an upwardly extendingapproximately vertical shaft 7 having a crank 8 provided with a terminalwrist 9. The shaft 7 is supported for rotation by the cross bar 4, theloops of the agitator resting flatwise on the screen 2 bar, which latteris spaced sufliciently above the screen to permit of the oscillation ofthe agitator.

Supported within the handle 3 is a double spring coil 10 havingintermediate the ends thereof a downwardly extending arm or yoke 11forming a loop which receives one end of a pitman 12, which has aflattened portion 12 loosely engaging the loop with which it is thusflexibly connected, said pitman being guided through the Wall of thescoop and terminally connected at its inner end with the wrist 9. Thelimbs of the yoke 11 are spaced slightly apart stantially parallel thedistance between the limbs being less than the diameter of the pitman orconnecting member 12, the flattened or reduced portion of which may thusbe readily introduced between the limbs and will be held securelyagainst displacement when introduced. The double spring coil 10 is connected with the upper portion of the handle, at a point distant from thewall of the scoop, and the lower end of the yoke 11 extends normally inthe direction of the wall of the scoop.

It will be seen that grasping the handle and the spring yoke andexerting pressure upon the latter, the pitman will be drawn outward,thus rocking or oscillating the shaft carrying the agitator in onedirection. When pressure on the spring yoke is released, the pitman willbe pushed inthereby shaft carrying the agitator in a reverse direction.This operation may be quickly repeated as often as may be needed by asimple pressure of the hand of the operator holding the scoop, and thecombined scoop and sifter may thus be manipulated with one hand, leavingthe other hand of the operator free to perform other work. This isespecially convenient in the making of batter and the like when one handmay be utilized for shifting the flour, while with the other hand thebatter may be stirred.

It will be seen from the foregoing that a construction is provided whichis exceedingly simple and in which the parts, when assembled willcooperate'efiiciently without danger of being accidentally separated.The resilient yoke which depends from the double spring coil is formedwith its limbs spaced very slightly apart and lying in substantiallyparallel relation throughout. The pitman or connecting member 12 havingthe flattened or reduced portion 12 is assembled with the yoke by simplyinserting the reduced portion between. the limbs thereof and sliding ittothe lower end of the yoke, this being done at some proper stage duringthe assemblage of the parts. The bridge piece at the lower end of theyoke will prevent the connecting member escaping in a downwarddirection, and longitudinal displacement is prevented owing to the factthat the yoke engaging portion of the pitman is reduced to a width aboutequal to the distance betweenthe limbs of the yoke, the terminals of thereduced portion forming shoulders or abutments engaged by the yoke. Thelower portion of the handle member 3 is Copies of this patent may beobtained for thus in no wise depended upon to maintain theparts inoperative condition.

Having thus described the invention, what is claimed as new, is

In a device of the class described, a scoop having a handle and a screenbottom, an agitator supported for rotation above the screen bottom andhaving a crank, a double coiled spring supported within the handle andhaving a yoke with substantially parallel limbs slightly spaced apartextending within the handle, and a connecting member guided through thewall of the scoop, one end of said member being connected with theagitator crank, and the other end of said member having a reducedportion engaging the loop of the yoke.

In testimony whereof I afiix my signature in presence of two witnesses.
